Comment:

A showy sprawling evergreen perennial in the mustard (Brassicaceae) family.  It is native to crevices of limestone rocks, along streams and in calcareous alpine meadows of Europe, Canada and parts of the northern U.S. from Maine to Wisconsin south to Tennessee. The blooms make excellent cut flowers.  The foliage is very attractive cascading over walls or in a rock garden and makes an effective groundcover.    Cut back foliage after bloom to promote denser growth habit.
